FREDERICK A. IVEGNER, OF THREE RIVERS, MICHIGAN.

CARRIAGE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 426,224, dated April 22, 1890.

Application filed September 17, 1888. Serial No. 285,639. (ModeL) To all whom it may concern.-

Be it known that I, FREDERICK A. WEGNER, a citizen of the United States, residing at Three Rivers, county of St. Joseph, State of Michigan, have invented a certain new and useful Improvement in Carriage-'Wrenches; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1. represents a perspective view of my improved carriage-wrench with the spriu gshank turned or twisted at right angles to itself on both sides of the nut-lock. Fig. 2 represents a perspective view of a portion of my wrench with the spring-shank flattened edgewise.

My invention relates to certain new and useful improvements on my carriage-wrench for which Letters Patent were granted to me October 9, 1888, No. 390,371.

It has been found that after attaching the wrench to the wheel and unscrewing the nut from the spindle, on screwing it on again in the same way, when the nut comes to its seat the sudden stoppage of the revolution of the wheel forces the hooks, or whatever means are used for attaching the wrench to the spokes, forcibly against the side of the spoke, thus denting or otherwise marring it.

It is the object of my improvement to provide a lateral springiness on the part of the wrench, so that on the nut reaching its seat and suddenly stopping the revolution of the wheel this lateral springiness will ease the suddenness of the pressure on the side of the spoke in stopping the revolution of the wheel. This may be accomplished in a number of ways, as I will now proceed to show.

In Fig. 1, A represents the nut-sockets of my carriage-wrench. B represents the springshanks provided at the ends with hooks 0, adapted to engage the spokes of the wheel. The spring-shanks B are on both sides of the nut-sockets A turned or twisted at b, so that while the main part of the spring-shank pre sents its face to the wheel the ends beyond the twisting-points Z1 will present their edges to the wheel. It will thus be seen that when the nut comes to its seat on the spindle and suddenly stops the revolution of the wheel this lateral spring I) in the main spring-shank of the wrench will prevent the pressure from coming suddenly onto the spoke, and thus dent or otherwise mar it, or twist off the end of the axle. So, also, in Fig. 2, where the springshank B is flattened out edgewise to form the lateral spring b, the same result is accomplished.

I have herein described but two means of accomplishing my object-viz, to provide a lateral springiness in my carriage-wrench, so that the suddenness of the stoppage of the revolution of the wheel incident to the nut having reached its seat and the consequent stoppage of the revolution of the wheel, might be eased and prevent the denting or otherwise marring of the spokes; but I do not limit myself to the means specified, as any means for accomplishing this purpose would be comprehended by my invention.

\Vhat I claim is- 1. In a carriage-wrench, the con'ibination, with a nut-socket, of spring-arms provided with hooks at their outer ends and extending from the socket, and said arms twisted at an angle at a point between the socket and their outer ends, whereby the arms may yield in the direction of the revolution of the wheel when the nut reaches its seat, substantially as set forth.

2. A wagon-wrench consisting of the combination, with a nut-socket, of a flat spring bar engaged therewith and projecting therefrom in both directions, with hooks at its ends for engaging the spokes, said springbar having its broad surface parallel with the plane of the spokes along a portion of its length and adapted along this portion to be sprung toward the spokes to engage the hooks, and having its broad surface along another portion of its length at right angles to the plane of the spokes and adapted along this portion to spring in the direction of the revolution of the wheel to cushion the wrench -when the nut is run to its seat, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
